No sound with Ubuntu on Chuwi Gemibook Pro
I just got a new Chuwi Gemibook Pro and installed Linux Ubuntu 21.04 on it, and there is no sound. In “Output device” I see only Dummpy output, and after adding
options snd-hda-intel model=generic
in
/etc/modprobe.d/alsa-base.conf
it changed to “HDMI / Display Port - Built-in Audio” but it still doesn’t work.
I tried different kernels (5.10, 5.11, 5.13) - all the same.
Unfortunately I removed Windows before checking the sound so I don’t know is it a hardware problem or not.
Here is some information, please ask if you need more:

Solution 1:
It is not hardware, as I am having the exact same issue on a Gemibook Pro, although on another distro, and there is a open bug on sof project. Even though that bug is initially for the Hi10X tablet, it is directly applicable to the gemibook pro, as it apparently has the same sound hardware, the ES8336 codec - [BUG] No local devices (speakers/headphones) on N4120 tablet (Chuwi Hi10X) #2955; there is a pull request linked at the end of the bug which indicates that support will come as soon as a driver is cleaned and pushed upstream. You can probably try it out by following the instructions for setting up a ktest environment and the pull request itself.
